Form 4
How does it work?
Separation of busbars from the functional units, and separation of all functional units from one another, including the terminals for external conductors which are an integral part of the functional unit.
Terminals for external conductors located in the same compartment as the associated functional unit. Busbar separation is achieved by insulated coverings, eg. Sleeving, wrapping or coatings. Cables may be glanded elsewhere.
Type 1
Terminals for external conductors located in the same compartment as the associated functional unit. Busbar separation is achieved by metallic, or non-metallic, rigid barriers, or partitions. Cables may be glanded elsewhere
Type 2
Terminals for external conductors located in the same compartment as the associated functional unit. Busbar separation is achieved by insulated coverings, eg. Sleeving, wrapping, or coatings. The termination for each functional unit has its own integral glanding facility.
Type 3
Terminals for external conductors located in the same compartment as the associated functional unit, but in individual, separate, enclosed protected spaces, or compartments. Busbar separation is achieved by insulated coverings, eg. Sleeving, wrapping or coatings. Cables may be glanded elsewhere.
Type 4
Terminals for external conductors located in the same compartment as the associated functional unit, but in individual, separate, enclosed protected spaces, or compartments. Busbar separation is achieved by metallic, or non-metallic, rigid barriers, or partitions. Terminals may be separated by insulated coverings, and glanded in common cabling chambers.
Type 5
Terminals for external conductors located in the same compartment as the associated functional unit, but in individual, separate, enclosed protected spaces, or compartments. All separation is by metallic or non-metallic, rigid barriers, or partitions. Cables are glanded in common cabling chamber.
Type 6
Terminals for external conductors located in the same compartment as the associated functional unit, but in individual separate, enclosed protected spaces, or compartments. All separation is by metallic, or non-metallic, rigid barriers, or partitions. The termination for each functional unit has its own integral glanding facility.
